In the rare case where kernel find all the # 8 primary hash slot occupied by bolted entries, this can result in hash page # table insert failure for bolted entries. Avoid this by using the secondary hash # group. # # This is different from what kernel does for the non-bolted mapping. With # non-bolted entries kernel will try secondary before removing an existing entry # from hash page table group. With bolted prefer primary hash group and hence # try to insert the page table entry by removing a slot from primary before trying # the secondary hash group. # # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20191024093542.29777-3-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 5a43800ff4cb810a1a67e301a496335dd7c06935 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/acpi.h:15, from /kisskb/src/include/linux/i2c.h:13, from /kisskb/src/include/uapi/linux/fb.h:6, from /kisskb/src/include/linux/fb.h:6, from /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:20: /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c: In function 'fsl_diu_ioctl': /kisskb/src/include/linux/device.h:1743:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1287:3: note: in expansion of macro 'dev_warn' dev_warn(info->dev, ^~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1290:2: note: here case MFB_SET_PIXFMT: ^~~~ In file included from /kisskb/src/include/linux/acpi.h:15, from /kisskb/src/include/linux/i2c.h:13, from /kisskb/src/include/uapi/linux/fb.h:6, from /kisskb/src/include/linux/fb.h:6, from /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:20: /kisskb/src/include/linux/device.h:1743:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1296:3: note: in expansion of macro 'dev_warn' dev_warn(info->dev, ^~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1299:2: note: here case MFB_GET_PIXFMT: ^~~~ INFO: Uncompressed kernel (size 0xe683a8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xf00000) Image Name: Linux-5.4.0-rc2-g5a43800ff4cb Created: Fri Oct 25 01:21:12 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6786465 Bytes = 6627.41 KiB = 6.47 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc8 # Build took: 0:02:20.057925
